Adjusting a Truing Stand
I need to figure out how to adjust my truing stand arms so that the right arm doesn't contact the rim before the left. I know it can be done, because while screwing around with it I switched the offset from the left arm to the right and now I need to center it. I'm using a Park TS-2. Any suggestions?

Adjust the caliper arm to center a 130mm spaced wheel. Narrower spaced wheels won't center on a TS-2.
I wrote a long explanation for why this is true but I "timed out" and my message was lost.

I don't see that the rim's width would make a difference unless it has an off-center design, and I don't have any of those either.
I make only very small adjustments to the caliper arm centering and only with a 130mm wheel on the stand. I reverse the wheel on the stand several times while truing to confirm proper dish.
With front wheels I set all spokes to the same tension and then make small truing adjustments.

The problem with using the calipers on a TS-2 to center wheels with various spacing is that the angle of the uprights changes as the span changes to accept wheels with different spacings. At 130mm the uprights are approximately perpendicular to the wheel axle and flush with the axle locknuts. When adjusted down to 100mm for a front wheel the uprights are not flush to the locknuts and due to the difference in size and shape of the locknuts the wheel will be pushed to one side or the other.
If you checkout a TS-3 truing stand you'll see that it is designed to keep the uprights parallel and perpendicular to the axle as the span is adjusted. I think Park needs to give up on their TS-2 and lower the price of the TS-3. The TS-2 just has too many design flaws.

I gave up on trying to adjust the TS-2 for anything other than 130 mm spaced wheels. For front wheels I set all spokes at the same tension, then make minor adjustments for radial and lateral true using either caliper but not both. To check dish I just flip the wheel on the stand and compare the fit between the rim and the calipers.

From a guy who used both -and some more like Minoura and Pedros- I got the hint that this one has a lesser tendency to go out of center. Since Iīm playing with it only since a few days now I cannot tell yet...

I used to just flip the wheel, I suppose that's crazy. I have a Var truing stand in the basement, talk about a nightmare. I would love to have a TS2. Is there really such a thing as a TS3? I don't see it on their website.
